2. Description of the Related Art In general, a drawer (drawer) of a drawer device used for a POS terminal or the like is provided with a coin storage section for storing coins on the near side and a bill storage section on the back side for storing bills. A bill storage unit is provided. Such drawers are usually locked by a lock mechanism and stored in the main body case of the drawer device, but are locked by a signal from a closing key or the like which is operated when the sales registration of the product is completed. The mechanism is unlocked, and the drawer is opened by receiving a force from a biasing means such as a spring built in the drawer device. In this case, there is a drawer device in which the drawer is not fully opened at once from the main body case, but is opened to the extent that the coin storage portion is exposed, and the bill storage portion is manually drawn out. This is because money is frequently exchanged with coins when conducting small transactions, and in such cases it is possible to store money and take out change without having to fully open the drawer. Also, this is to reduce the burden of storing operation of the drawer in the main body case. In addition, there is also a meaning that crimes are prevented by preventing high-value bills from being seen by human eyes, and a meaning that the impact of a drawer that has been urged by the urging means and jumped out is mitigated.
